To all whom it may mm Be itknown thatfl, JoHN O. sees, a citi-- Z n of the United Statespresiding at Marvin, in the county of l/lorganandState. of,M1{s' souri, ha v invented certain new and-useful.

Improvements in Force-Feed Lubricators the "art tdwhich it appertains to'm'ake and use the same.

M 7 invention relates to force feed lubricators, andparticularly to that class having automatic action. 4 I lily object is to supply anfloilr','tha t will supply a positive and regular flow of lubricant at all times, and requiring but little attention. i 7

in the drawing herewithillustrating my invention and which is made a part of this application, I have shown a side elevation with a vertical sectional view of the oil con tainer and the ducts leading therefrom.

A frame 1 supporting the lubricator and the operating mechanism of the forced feed, is mounted upon the duct 2, said duct leading to the part to be lubricated.

The oil container comprises an inverted cup 4 and a member 3 serving as a closure for the cup 4. The member 3 is screw threaded on the outside at the point of its greatest diameter. The cup 4 is screwthreaded throughout its length upon the inner side tlvreof, the threads on the member 3 engage the thread in the cup 4, whereby the said cup is caused to move downwardly upon the member 3 as the cup 4 is rotated. For convenience of removing member 3 from the frame so that the cup 4 may be more readily filled with oil, the lower end 5 of the member 3 is screw-threaded, these threads are cut in an opposite direction from the threads on the upper end of the member 3 so as to prevent it unscrewing when the cup 4 is turned on the member 3. Said member 3 has an aperture or duct extending throughout its entire length, to provide a passage for the oil from the cup 4 to the part tobe lubricated.

Attached to the center of the top of the cup 4 is a stem 6 extending upwardly through the pinion 8. Said stem 6 is provided with a key seat 7 throughout its entire length. Positioned on this stem is a pinion 8 having a worm gear, the said pinion 8 is slidably mounted upon said stem 6 and to Specification of ietters'Patent. i P teyit dNd ,93915 a ease filed September 1, 1914; seritrim}s5;-a' e Pr si'turning as the said stem a loosely fitting ltey' (not shown) is inserted "in; the f key'seat but said key'is 'securelytltted in the hubo'f said pin on 8; The saidpinion. 8'

has an upwardly extending"elongated'hub' rich extendsthrough "the. upper cross bar and I do hereby declare the followingfto be. a full, clear, and exact description ofthe in= vention, such as will enable others slrilled'in of the frame 1 andfis journaled therein, The

said hubfex'tendsfthrough the said frame a' 3 sufficient distanceto permit a collar 10..t0 be mounted thereon, said collar is s'eciire d to; sa d hi b by means of "aset-sorew 11 where the saidhub enters the fra'ine, thediameter of the hiib' reduced to form a shoulder 12 thereon. [This shoulder 121 nd the collar 10"'se'rvesfto hold thepinio in its vproper voperative position and permits the stein 6 to be "drawnthrough it the action of the screw-threads on the member 3 and the cup At the extreme upper of the V stem 6' a crank is secaredio provide a'means for qu k rei i e' t e c p ezvh n i requires ire-filling.-

Connected to the lower end of the member 7 3 is a nipple 1.3 inserted in the frame which is screw-threaded to the duct 2, said nipple is provided with an aperture therethrough for the passage of oil from the member 3 to the duct 2. A counter shaft 14 is secured to the frame transversely to the stem '6, said counter shaft 14 being journaled in the boxings 15 and 16. Mounted on the central portion of the said counter shaft 14 is a wormv gear 15 securely keyed thereon. Said wormgear being intended to engage the gear on the pinion 8 and to rotate the said pinion 8. The end of the counter shaft 14 extends beyond the boxing 16 and has, loosely mount;

ed thereon an arm 17. Just beyond the bearing of the arm 17 the end of the counter shaft is reduced to form a shoulder. Upon the reduced part a ratchet wheel 19 having notches in its periphery is mounted and is secured to the counter shaft 14 by a nut 20 1 having a handle 21 attached thereto.

Pivotally attached to the arm 17 adjacent the rim of the wheel 19 is a catch 22, mounted on the pivot 23, said catch being held in operative position by the counter weight 24, said counter weight being the enlarged lower end of the catch. The free end of the arm 17 is attached to a reciprocating part 25 of the machine on which the lubricator is located. The movement of this part is communicated to the arm .17, as the said armmoves backrdly and forwardly the catch engages the notches of the wheel 19 and moves it around which turns the counter shaft 14:, the shaft turns, through the Worm gear 8 and 15, the stem 6 and the cup 4. Said cup through the action of the screw threads therein is moved downwardly exerting a pressure on the oil in the cup 4 forcing a continuous feed of oil through the ducts'in; the member 3 and the nipple 18. of oil the nut 20 on the shaft'l is loosened which allows the Wheel 19 to turn on the V shaft 14% Without turning the shaft;

From the foregoing description it will be seen that I have designed an automatic forced-feed oiler for using hard oih one that requires onlytobe kept filled to enable it to perform the function designed for it with out further attention, and one adapted for use in inaccessible places on this account.

Believing that the construction, advantages and manner of using myinvention have thus been made clearly apparent, further description is deemed unnecessary.

Having thus fully described my invention, What I desire to secure by Letters-Patent is 1. A'lubricator comprising a supporting frame; an inverted oil cup vertically movable Within said frame and having screwthreads upon its inner surface; a fixedly If it is desired to stop the flowv mounted closure for said cup having screw threads on its outer-edge, and an aper are extending throughout its length; an upwardly extending stem attached to said cup and provided With a key Way, and means slid-ably keyed to said. stem to rotate said stem and said cup.

, 2. 23. lubricator comprising a supporting frame; an inverted oil cup having screwthreads upon its inner surface; a fixedly mounted closure for said cup, having screw threads on its outer edge, and an aperture extending throughout its length; an upwardly extending stem attached to said cup; a counter shaft attached to said frame;

worm gears mounted on said stern and said a counter-shaft; a swinging arm loosely mounted. on, sa d counter shaft, outside of said frame; a ratchet Wheel detachablymountedon the end of said counter shaft,

and a latch attached to said swinging arm and engag ng the said-ratchet Wheel.

In testimony whereof l have signed my name to this specificationin the presence of A two subscribing: Witnesses.
